         java.util.Map<java.lang.String,AttachmentValue> attachments,
         Timestamp timestamp)

Description copied from class: MutableAggregation

Put a new value into the MutableAggregation.

Specified by:

add in class MutableAggregation

Parameters:

value - new value to be added to population

attachments - the contextual information on an Exemplar

timestamp - the timestamp when the value is recorded

combine

void combine(MutableAggregation other,
             double fraction)

Description copied from class: MutableAggregation
